Abstract

Several noise muffler cells are incorporated to form exhaust muffler units possessing set end efficiency ratios. The cast aluminum cells have their noise-damping properties determined by the inner or outer or combined shaping, plus by means of mechanical treatment, filling with suitable materials or both. The cells are screwed to form the units and can be dismantled.

Description

Die heute im KFZ-Bereich verwendeten, geschweißten Stahlblech-Auspufftöpfe haben vor allem den Nachteil schneller Korrosion (oft schon vor dem Einbau), sie werden dadurch defekt. Aufgrund der Bauweise ist es nicht möglich, diese Auspufftöpfe zu Öffnen. Reparaturen sind nur ungenügend am äußeren Gehäuse möglich, meistens jedoch garnicht. Edelstahl-Auspufftöpfe sind zwar dauerhafter, können aber aus den genannten Gründen ebenfalls nicht zufriedenstellend repariert werden. Sie sind auch viel teurer als die meistverwendeten Stahlblech-Auspufftöpfe. Kaputte Auspufftöpfe müssen mühevoll demontiert und entsorgt werden.The welded sheet steel mufflers used in the automotive sector today have plans all the disadvantage of fast corrosion (often before installation), they become malfunction. Due to the design, it is not possible to open these mufflers. Repairs are only insufficiently possible on the outer housing, but mostly not at all. Stainless steel mufflers are more durable, but can be made from the above Reasons not be repaired satisfactorily. They are also much more expensive than the most widely used sheet steel mufflers. Broken mufflers have to be painstaking disassembled and disposed of.

Korrosionsanfällige, rostende Auspufftöpfe entsprechen nicht mehr dem hohen Quali­ tätsstandard der KFZ-Industrie. Die Herstelltechnik ist unzweckmäßig und belastet die Umwelt unnötig. Außerdem ist für Herstellung, Montage, Verwaltung und Entsorgung tausender verschiedener Typen mit sperrigen Abmessungen ein hoher Kostenaufwand erforderlich.Corrosion-prone, rusting mufflers no longer correspond to the high quality standard of the automotive industry. The manufacturing technology is inappropriate and burdens the Environment unnecessary. It is also responsible for manufacturing, assembly, administration and disposal thousands of different types with bulky dimensions a high cost required.

Die Zeichnung Blatt 3 zeigt ein Ausführungsbeispiel erfindungsgemäß vorgeschlagener Schalldämpfer-Bauzellen. Die Erfindung beseitigt die genannten Nachteile. Durch vorzugsweises Verschrauben mehrerer Bauzellen mit bestimmten eigenen Dämpfer-Wirkungsgraden miteinander unter evtl. Einbeziehen geeigneter Abdichtungen z. B. zwischen den Bauzellen können Schalldämpfer-Aggregate (Auspufftöpfe) mit gewünschten Schalldämpfer-Endwirkungsgraden hergestellt werden.The drawing sheet 3 shows an embodiment proposed according to the invention Silencer modules. The invention eliminates the disadvantages mentioned. By preferably screwing together several building cells with specific ones Damper efficiencies with each other, possibly including suitable seals e.g. B. between the building can silencer units (mufflers) with desired silencer end efficiencies.

Die Schalldämpfer-Bauzellen werden vorzugsweise aus ALU-Guß einfacher und kostengünstiger als bisher produziert. Sie sind verschleißfest und trotz der agressiven Belastungen korrosionsbeständig und dauerhaft. Sie werden z. B. als Resonanz- bzw. Reibungs-Schalldämpfer-Bauzellen mit festgelegten Schalldämpfer-Wirkungsgraden gefertigt, welche u. a. von der inneren bzw. äußeren Bauzellenform und -Ausstattung bestimmt sind, wobei je nach Erfordernis diese Wirkungsgrade durch z. B. zusätzliche mechanische Bearbeitung noch individueller angepaßt werden können.The silencer modules are preferably made of cast aluminum and simpler produced more cheaply than before. They are wear-resistant and despite the aggressive Corrosion-resistant and permanent loads. You will e.g. B. as a resonance or Friction silencer modules with specified silencer efficiencies manufactured which u. a. of the inner and outer shape and equipment of the building are determined, depending on requirements, these efficiencies by z. B. additional mechanical processing can be customized.

Durch gleichbleibende Formgenauigkeit des Alugusses und einheitliche Maße können die Bauzellen beliebig miteinder kombiniert und zu Schalldämpfer-Aggregaten verbunden (verschraubt) werden. Dabei addieren sich die einzelnen Wirkungsgrade jedes Aggregats entsprechend der Anzahl ihrer Bauzellen zu den gewünschten Gesamtwirkungsgraden, wie sie z. B. für verschiedenste KFZ-Hersteller und KFZ-Typen erforderlich sind. Um Schalldämpfer-Aggregate mit erforderlichen Schalldämpfer-Endwirkungsgraden zusammenzustellen, sind relativ wenige Schalldämpfer-Bauzellen mit eigenen, serien- bzw. typabhängigen Wirkungsgraden erforderlich.Due to the constant shape accuracy of the cast aluminum and uniform dimensions, the Modules combined with each other as required and connected to silencer units (screwed). The individual efficiencies of each unit add up according to the number of their cells to the desired overall efficiency, as they e.g. B. are required for various vehicle manufacturers and vehicle types. To muffler units with required muffler end efficiencies there are relatively few silencer modules with their own, series or type-dependent efficiencies required.

Herstellung, Verwaltung, Transport, Lagerhaltung usw. werden dadurch bedeutend einfacher, übersichtlicher und kostensparender.Manufacturing, administration, transport, warehousing, etc. become important easier, clearer and less expensive.

Das Erfindungsprinzip ist auch realisiert, wenn zwischen den Bauzellen bzw. in diesen zusätzlich z. B. Rohranschlüsse, Katalysatoren o.a. Fremdelemente integriert bzw. angebracht sind. Eventuell defekte Schalldämpfer-Bauzellen lassen sich mit üblichem Werkzeug öffnen und sehr geringem Aufwand austauschen. Die Bauzellen können außen und innen mit üblichen Mitteln gereinigt werden.The principle of the invention is also realized when between or in the building cells additionally z. B. pipe connections, catalysts, etc. Foreign elements integrated or are attached. Any defective silencer modules can be removed with the usual Open the tool and replace it with very little effort. The building cells can be outside and cleaned inside with usual means.

Durch Nutzung der innovativen, erfindungsgemäßen Schalldämpfer-Bauzellen ist es möglich, den heutigen, hohen Qualitätsstandard der KFZ-Industrie nochmals wesentlich zu verbessern. By using the innovative silencer modules according to the invention, it is possible, today's high quality standard of the automotive industry again essential to improve.
